Every house i’ve Lived in had one of these ; not particularly pretty . On large building sites I don’t see any . I assume it’s a requirement so how do they do a ‘hidden’ stench pipe ???

There is no keen price anywhere!!

Can’t you invent a noiseless flow regulator for at source? . Dragons Den will back you ??

Can I ask @Nickfromwales out of interest ; why attenuate at outlet not source ? . What’s the issue ? Or is it just bad practice?

Ah ! So I have mid understood ! I assumed quite naturally they could do both I.e that was their function . Well attenuation at a outlet shouldn’t be an issue . For now i’ll Just stick ‘em all full on once ready for take off ! Boom ! - bet @Onoff took 6 months to do that bit ????

I’ll do the hot one tomorrow- too much excitement for one day !

Really ? They generate that much noise if not fully open or fully closed ? . That was one of my reasons for choosing these nice expensive brass manifolds - thinking I could be clever and control flow ?

Well it ain’t pretty but timber allows a Hep2o clip per pipe . Going under the render board ‘lines’ the pipe up to run across the ceiling . Not sure how good this will be really . Need to run a ‘ real’ pipe and see ...

Actually I could ‘throttle’ the outside tap ( planned to do this on toilets anyway ) by adjusting the isolator value to restrict flow .

Didn’t think of that . Outside tap will hardly ever be used so i’ll Let it go ?

Labelling to my hearts content !

Just done my 16 vertical holes . Ordered washing machine waste to act as conduit . Just making up the manifold . Photos later

Not sure where someone like you would pick up such ‘tricks’ . 4 25mm holes drilled . 16 to go

Yep I checked this as it was an option for me . Vertical or horizontal no issue .

I am aren’t I !!

Will have a suspended ceiling .

Googling seems to range from 16mm to 20mm . If that’s correct would be good !

What’s the diameter of a dishwasher waste pipe ? . Just bought a 25mm drill bit - so if it fits in that ( and Hep2o in dishwasher pipe ) then perfect !

Not sure. Ordered a few 'cold bends' to see. Sure they will come in useful somewhere!

I could. But I've got about 20 pipes to get through this wall. Thought it would be easier going vertical through the wall then up. Also I can line up each pipe to the manifold so it runs horizontal into it. I'll attempt a "1st go" tomorrow and post pics. I'm guessing as I have a false ceiling the pipe might 'naturally' curved ok at that point.

Please. Will the scale model take 4 years also? ?

From my other thread...

Yeah - that’s why I was making the hole larger so perhaps I can put some kind of sleeve around it .

Yeah I guess so . Still a tight turn at the ceiling - but a good point !

Erk no ! Got a geberit pan going on the end wall already . i’ll just do a 1000 x 1000 or similar door’d Cubicle for the shower .
